3-D 3-D IMAGE ANALYZER FOR DETERMINING VIEWING DIRECTION

摘要

A 3D image analyzer for determining a gaze direction or line of sight in 3D space (including a gaze direction and a position vector indicating, for example, where the pupil midpoint and gaze direction vector start), comprises a first set of image data Wherein the first image comprises a pattern for displaying a three-dimensional object from a first viewpoint into a first image plane and the further set comprises a second viewpoint from a further viewpoint into a further image plane Dimensional object, or an additional set includes image information and / or a relationship between at least two points of the first image and / or at least position information. The image information is determined based on the first image or one or more additional images. The position information describes the relationship between at least one point of the three-dimensional object and the first image plane. The 3D image analyzer includes a position calculator and a sort calculator, and uses them to calculate the gaze direction in 3D space.
